Ya got skinheads and militia groups and racist groups and bigorty groups and misogynistic groups whose entire life is devoted to hate and planning how to take out those they hate? Who protects us from them? They are American citizens who have every right to be here. Why not rout them out too and ship them out to somewhere else so that they can't hurt us? Being an American citizen does not confer goodness upon anyone. Just as being a foreigner/immigrant doesn't confer evil on anyone either..
